Chapter 6 Muting 2-Sensor T-Type Bidirectional
Machine Layout
The material can flow in either direction: to the hazard area from the non-hazard
area or reverse. The shape of the material must be such that it blocks both muting
sensors before it blocks the light curtain. The order in which the muting sensors
are blocked is not critical, but the synchronization time (time between blocking
one sensor and the other sensor) must be met.

The example schematic is set up to agree with the terminals shown in the
Connected Components Workbench software and the example bill of materials.
